To all whom it may concern: a

Be it known that I, DAVID F. PRISER, a citizen of the United States, residing at North Manchester, in the county of Wabash and State of Indiana, have invented new and useful Improvements in Water-Heating Devices, of which the following is a specificatio This invention relates to water heaters and has for an object the provision of means for utilizing water or steam of a heating. plant for the purpose of heating water in a water supply system.

Another object of the invention is the provision of means for the above purpose Which is simple in' construction and which may be connected both in a heating system and a Water supply system, whereby water in the latter maybe subjected $05 the heat of the former, first for initialheating and again for final heating, in the passage of said Water through the water system.

With the above and other objects in View, the invention further includes the follow- 35 ing novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the. appended claims.

In the drawings:

J Figure 1 is an elevation of the invention.

Figure 2 is a longitudinal sectional view of the same.

Figure 3 is a transverse section. Referring in detail to the drawings,

wherein like characters of reference denote corresponding parts, the reference character 10 indicatesacasing which may be of any desired length and which includes an inner passage 11 and an outer passage 12, the said passages extending longitudinally ofi the casing and being closed at their ends.

To provide a casing of this structurethere is utilized an inner cylindrical memberor pipe 13 and an outer cylindrical member or pipe 14., the former extending through and supporting the latter. Extending from the pipe 13 and communicatin with the inner passage 11 is a pipe 15, which is adapted to be connected in the distributing system of a steam or hot water plant, so that steam or water from the latter may enter and travel through the passage 11. At theoppoite end of the casing and connected to the inner pipe 13 so as to communicate with the quantitydesired.

inner passage 11 is a pipe 16 which may form a suitable source of distribution to the radiator or radiators'o-f the heating lant. Extending longitudinally through t e inner passage 11 'is a pipe 17 which may be connected with a suitable source of water supply, such as the water sup ly system of a building, the opposite end 0 this pipe ex tending through the opposite end of the casing and being connected to the outer pipe 14 so as to provide communication with the outer passage 12, asshown at 18. Suitable reducing nlpples or similar elements 20 may be provided for mounting and supporting the casing 10 upon the plpe 17.

Extending from the casin o posite the point of connection 18 is a' isdliarge pipe or outlet 21 from which extends a pipe 22 and this last mentioned pipe is adapted to provide means of water distribution, a dirt trap 23 being preferably connected at the juncture of the pipes 21.and 22.

' It will be apparent from the foregoing description and accompanying drawings that steam or hot water passing into the casing through the pipe 15 will travel through the inner passagev 11, while water from a water system or other source of supply passing through that portion of the pipe 17 within the casing will be subjected to heat from the water or steam within the passage 11, where it will be initially heated. This water will then enter the casin through the connection 18 and pass throu 1% the outer passage 12 and will be again su jected toheat fro-m the water or steam passing through the passage 11, so that heating of water passing through the water supply system will bethoroughly and practically instantaneously heated. The heated water may then be conducted to a suitable point or points through the distributing pipe 22. The invention Will thus provide means which may be connected within a heating system and water supply system, whereby water drawn from the latter will be instantaneously and thoroughly heated in any The invention is susceptible of various changes in its form, proportions and minor details of construction and the right is here- 5 in reserved to make such .changes'as prop- Zfly fall within the scope of the appended aim.

. 5 nectin Having described the invention what claimed 1s:- v l A water heater comprising spaced inner and outer cylinders, spacing nipples conthe inner and outer cylinders and provi mg an outer water passage closed at each end and an inner steam passage, said steam passage having steam inlet and outlet .ports, means closing the opposite ends of the steam passage, a water supply pipe extending longitudinally through the steam passage and havin one of its ends in communication with t e water passage at one end thereof and having a water outlet adjacent its opposite end.

In testimony whereof I aflix my signature.

DAVID F. PRISER.
